构建包含ASM模块的C代码的错误

我正在尝试为Wire Maxim协议构建App Note AN1199。这是一个带有几个头文件的单个源代码文件。其中的一个头具有软件设计用于PIC的include文件，因此我把它更改为PIC（24FJ64GB002）。另一个头文件有一些ASM模块。一个例子是：当我尝试构建时，我得到了一些提示未声明的_asm函数的错误，但是我无法找出任何错误。很多年前，我只尝试过几行汇编，但我认为我的大脑把这些记忆封闭起来作为某种防御机制。以下是错误信息：执行：“C:Program FilesMicro.MPLAB C30binpic30-gcc.exe”-mcpu=24FJ64GB002-x c-c“1-Wire App Note Source Code1..c”-o“1..o”-D_DEBUG-g-WallIn文件，包括在1-线应用说明源码1-线应用注释源代码\1Wi线源码\1Wi线应用源码\1wire1Wi线应用源码\1wire1Wi线应用源码1wire1..c:45:45:1-1-线应用说明源码\1.App布线应用说明源码\\1..45:45:45:1:1:1:1:1:1:1-线应用说明源码1-线应用说明源码\未申报首先在这个函数中使用)1-Wire App Note Source Code1..c:115:error：（每个未声明的标识符只报告在1-Wire App Note Source Code1..c:115:error：对于每个函数它出现在。）1-Wire App Note Source Code1..c:115：error：movlw'1-Wire App Note Sou之前的语法错误rce Code1..c:120:error:在“movlw”1Wire App Note Source Code1..c:124:error:在“movlw”1-Wire App Note Source Code1..c1..c:In function'OW_write_bit:1-Wire App Note Source Code1..c:120:error:“_asm”之前的语法错误（在此函数中首次使用）1-Wire App注意，源代码1..c:147:error:在“movlw”1-Wire App Note Source Code1..c:149:error:在“movlw”1-Wire App Note Source Code1..c:155:error:在“movlw”1-Wire App Note Source Code1..c:147:error:在“movlw”1-Wire Ap Ap之前的语法错误p Note Source Code1..c：在函数'OW_read_bit':1-Wire App Note Source Code1..c:176:error: '_asm'unsclared(在这个函数中首次使用)1-Wire App Note Source Code1..c:176:error:movlw'1-Wire App Note Source Code1..c:178:error:movlw'1-1.'1之前的语法错误-Wire App Note Source Code1..c:182:error:movlw'1之前的语法错误-Wire App Note Source Code1..c:230:95:warning:文件末尾没有换行



      以下为原文

    I'm trying to build the App Note AN1199 for 1 Wire Maxim Protocol.

This is a single source code file with a couple of header files. One of these headers has the include file for the PIC that the software was designed for, so I changed it to my PIC (24FJ64GB002). Another of the header files has some ASM modules. A sample being :
#if(CLK_FREQ_25000000)
  #define wait(a) _asm movlw a
       movwf macro_delay,1
     loop: nop
       nop
       nop
       decfsz macro_delay,1,1
       bra loop
      _endasm
      
  #define BAUD_RATE 39
When I try to build I get errors suggestive of undeclared _asm functions, but I can't figure any of it out. I only attempted a few lines of Assembly , many years ago but I think my brain shut those memories out as some sort of defensive mechanism.Here's the error messages:
